Professor Željko Pedišić has joined the School of Public Health of the University of Hong Kong after 19 years of service at the University of Graz (Postdoctoral Research Fellow), University of Sydney (Postdoctoral Research Fellow), University of Zagreb (Senior Research Fellow / Senior Lecturer in Quantitative Methods), and Victoria University (Professor and Leader of the Active Living & Public Health research group). He is the President of the International Network of Time-Use Epidemiologists (INTUE), with >200 members from 42 countries.

His research is centred around chronic disease prevention and promotion of well-being through healthy use of time. His interests span: prevalence, determinants, and outcomes of unhealthy time use; statistical and measurement methods in time-use epidemiology; and public health surveillance, policies, and interventions. He is the author of the Activity Balance (AB) model, Comprehensive Analysis of Policy on Physical Activity (CAPPA) framework, and Viable Integrative Research in Time-Use Epidemiology (VIRTUE) framework. He has been at the forefront of a major paradigm change in physical activity, sedentary behaviour, and sleep research, resulting in the development of time-use epidemiology as a new research field and widespread adoption of Compositional Data Analysis (CoDA) in public health research.

He has authored >140 full-text publications, of which ∼60% as the first, senior and/or corresponding author and ∼20% as the second author. As a supervisor and methodological consultant, he has contributed to 4 bachelor, 25 master, and 17 PhD research theses. He has repeatedly achieved outstanding success in research dissemination, including authorship of two journal articles with Altmetric scores of ∼3500 and guest interviews with large news media, such as BBC, CNN, Discover Magazine, Healthline, Popular Science, The Guardian, and TIME Magazine.
